public void setTextColor(int color) { 
    mTextColor = ColorStateList.valueOf(color);  
    updateTextColors();  
}  
  
public void setTextColor(ColorStateList colors) {  
    if (colors == null) {  
        throw new NullPointerException();  
    }  
  
    mTextColor = colors;  
    updateTextColors();  
}  
 

下邊就分別寫出怎麼使用這兩個方法設定TextView的顏色：

TextView tv = new TextView(this);  
tv.setText("Test set TextView's color.");  
//方案一：程式碼中通過argb值的方式  
tv.setTextColor(Color.rgb(255, 255, 255));  

這種方法也就是傳入int color值，這個int不是R檔案中自動分配的int值，所以要注意。這是Color類中的靜態方法構造出來的顏色int值。

Resources resource = (Resources) getBaseContext().getResources();  
ColorStateList csl = (ColorStateList) resource.getColorStateList(R.color.my_color);  
if (csl != null) {  
    tv.setTextColor(csl);  
}  
 

這種方法是通過ColorStateList得到xml中的配置的顏色的。好多需要xml中配置的都要類似這樣的對映xml檔案。

還有種方法Java程式碼:

XmlResourceParser xrp = getResources().getXml(R.color.my_color);  
try {  
    ColorStateList csl = ColorStateList.createFromXml(getResources(), xrp);  
    tv.setTextColor(csl);  
} catch (Exception e) {  
}  

 全部程式碼Java程式碼 :

package com.txlong;  
  
import android.app.Activity;  
import android.graphics.Color;  
import android.os.Bundle;  
import android.widget.TextView;  
  
public class ListViewDemoActivity extends Activity {  
    // private ListView listView;  
  
    /** Called when the activity is first created. */  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
  
        TextView tv = new TextView(this);  
        tv.setText("Test set TextView's color.");  
        //方案一：通過ARGB值的方式  
        /** 
         * set the TextView color as the 0~255's ARGB，These component values 
         * should be [0..255], but there is no range check performed, so if they 
         * are out of range, the returned color is undefined 
         */  
//      tv.setTextColor(Color.rgb(255, 255, 255));  
        /** 
         * set the TextView color as the #RRGGBB #AARRGGBB 'red', 'blue', 
         * 'green', 'black', 'white', 'gray', 'cyan', 'magenta', 'yellow', 
         * 'lightgray', 'darkgray' 
         */  
        tv.setTextColor(Color.parseColor("#FFFFFF"));  
          
          
        /** 原來不知道有上邊的方法，就用這個笨笨方法了 */  
//      String StrColor = null;  
//      StrColor = "FFFFFFFF";  
//      int length = StrColor.length();  
//      if (length == 6) {  
//          tv.setTextColor(Color.rgb(  
//                  Integer.valueOf(StrColor.substring(0, 2), 16),  
//                  Integer.valueOf(StrColor.substring(2, 4), 16),  
//                  Integer.valueOf(StrColor.substring(4, 6), 16)));  
//      } else if (length == 8) {  
//          tv.setTextColor(Color.argb(  
//                  Integer.valueOf(StrColor.substring(0, 2), 16),  
//                  Integer.valueOf(StrColor.substring(2, 4), 16),  
//                  Integer.valueOf(StrColor.substring(4, 6), 16),  
//                  Integer.valueOf(StrColor.substring(6, 8), 16)));  
//      }  
          
        //方案二：通過資源引用  
//      tv.setTextColor(getResources().getColor(R.color.my_color));  
          
        //方案三：通過資原始檔寫在String.xml中  
//      Resources resource = (Resources) getBaseContext().getResources();  
//      ColorStateList csl = (ColorStateList) resource.getColorStateList(R.color.my_color);  
//      if (csl != null) {  
//          tv.setTextColor(csl);  
//      }  
  
        //方案四：通過xml檔案，如/res/text_color.xml  
//      XmlPullParser xrp = getResources().getXml(R.color.text_color);  
//      try {  
//          ColorStateList csl = ColorStateList.createFromXml(getResources(), xrp);  
//          tv.setTextColor(csl);  
//      } catch (Exception e) {  
//      }  
          
        // listView = new ListView(this);  
        //  
        // Cursor cursor = getContentResolver().query(  
        // Uri.parse("content://contacts/people"), null, null, null, null);  
        //  
        // startManagingCursor(cursor);  
        //  
        // ListAdapter listAdapter = new SimpleCursorAdapter(this,  
        // android.R.layout.simple_expandable_list_item_2, cursor,  
        // new String[] { "name", "name" }, new int[] {  
        // android.R.id.text1, android.R.id.text2 });  
        //  
        // listView.setAdapter(listAdapter);  
        // setContentView(listView);  
        setContentView(tv);  
    }  
}  

String.xml檔案為：

<?xml version="1.0" encoding="utf-8"?>  
<resources>  
  
    <string name="hello">Hello World, ListViewDemoActivity!</string>  
    <string name="app_name">ListViewDemo</string>  
  
    <color name="my_color">#FFFFFF</color>  
  
</resources>  

/res/color/text_color.xml 程式碼  :

<?xml version="1.0" encoding="utf-8"?>  
<selector xmlns:android="http://schemas.android.com/apk/res/android">
